چکیده
In the centrosymmetric binuclear title compound, [Pb(2)(N(3))(2)(NCS)(2)(C(12)H(8)N(2))(4)], the N-donor atoms of one N-heterocycle and the N-donor atom of a thio-cyanate anion along with the sterically active lone-pair electrons comprise an approximate square; a plane through three atoms of this square is twisted slightly with respect to the square made up of the other four atoms (two from the other N-heterocycle and one each from the bridging azide anions) at a dihedral angle of 18.7 (1)°. The Pb(II) atom is in a Ψ-square-anti-prismaic coordination.

The title coordination polymer, [Pb(2)(N(3))(3)(NO(2))(C(12)H(8)N(2))(2)](n), has as the repeat unit a centrosymmetric dinuclear mol-ecule having azide and nitrite groups that bridge adjacent heterocycle-coordinated metal centers. One of the azide group uses its terminal ends to bridge whereas the nitrite group chelates to one metal atom and uses one of its O atoms to bridge. The azide and nitr...

In the title complex, [Cd(2)(NCS)(4)(C(13)H(19)N(3)O)(2)], the two Cd(II) ions are bridged by a pair of thio-cyanate N:S-bridging ligands around an inversion center. One terminal thio-cyanate N atom and one N,N',N''-tridentate Schiff base ligand complete a distorted CdN(5)S octa-hedral geometry about each Cd(II) atom. In the crystal, the Schiff base aromatic rings of adjacent mol-ecules are arr...

The title compound, [Cd(NCS)(2)(C(6)H(5)N(5))(2)](n), is a coordination polymer with the Cd(II) centre located on a twofold rotation axis. The Cd(II) centre assumes a distorted octa-hedral geometry. The thio-cyanate anions function as bridging ligands between the Cd(II) centres, leading to a chain-like arrangement expanding along [001].

In the crystal structure of the title complex, [Cd(N(3))(2)(C(11)H(11)N(31))(2)](n), there are two crystallographically independent Cd(II) atoms. Both exist in an octa-hedral environment composed of four N atoms of the N(3) (-) groups and two N atoms from two monodentate 1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one ligands that are positioned trans to each other. Adjacent Cd(II) centres in th...
